The 12x56 Savannah ED Binocular from Barr & Stroud combines a fully multicoated extra-low dispersion (ED) lens system, large objectives and phase-corrected BaK4 prisms to create a color-faithful high-transmission optical path built for low light performance. This 12x handheld optic features an immersive 66° apparent viewing angle and has the ability to focus within ten feet, making the Savannah ED ready for almost any intermediate to long-range glassing task.

In addition to the image quality rendered by their premium optics, this Savannah ED configuration also has a long 16mm eye relief and twist-up rubber eyecups with multiple click-stop positions. A rapid focus wheel allows the observer to focus from close-up to infinity within a single rotation. Additionally, Barr & Stroud's individual diopter control, located next to the focus wheel, helps the observer calibrate the oculars for their eyesight. Complementing the 12x56 high-transmission optics and handling features is a nitrogen-filled fogproof housing; Savannah ED binoculars are submergible to five feet (for up to three minutes) and are wrapped with slip-resistant rubber armor that absorbs light impact.
